NOTE A: Boot ROM: If the boot ROM is enabled, then addresses 0000
00FF in the program space will be occupied by boot ROM.
Addresses 0040h
0043h in program memory are reserved for code security passwords.
When CNF = 1, addresses FE00h
FEFFh and FF00h
FFFFh are mapped to the same physical block (B0) in program-memory space. For
example, a write to FE00h has the same effect as a write to FF00h. For simplicity, addresses FE00h
FEFFh are referred to as reserved.
§
When CNF = 0, addresses 0100h
01FFh and 0200h
02FFh are mapped to the same physical block (B0) in data-memory space. For example,
a write to 0100h has the same effect as a write to 0200h. For simplicity, addresses 0100h
01FFh are referred to as reserved.
Addresses 0300h
03FFh and 0400h
04FFh are mapped to the same physical block (B1) in data-memory space. For example, a write to 0400h
has the same effect as a write to 0300h. For simplicity, addresses 0400h
04FFh are referred to as reserved.
